[sdiy] Retrofitting a PS-3100 with an Arduino

[ulfur hansson]

i couldn’t help myself - hand soldered 48 gates already and screwed them in there.... i was a bit worried about the extra draw on the 10v rail but no problems so far.... definitely the easiest midi retrofit i’ve ever attempted!

   i couldn't help myself - hand soldered 48 gates already and screwed
   them in there.... i was a bit worried about the extra draw on the 10v
   rail but no problems so far.... definitely the easiest midi retrofit

        first post here, - hello!Â
        I recently managed to acquire a PS-3100 in great condition. it is
     fully
        operational, and i've been having a lot of fun tracking with it,
     it is
        an immensely powerful instrument!
        i couldn't help myself but open up the back panel right away, and
        happened to have a midi controlled "gate" sketch uploaded on
        my arduino MEGA on my workdesk(each pin going HIGH on
     corresponding
        note ON message received).
        looking through the PS-3100 service manual it looks like I need
     10V
        gate signals to trigger each individual note - i put together a
     simple
        single transistor configuration to expand the arduino logic up
     to 10v
        - alligator clipped a few pins to the inside of the 60pin honda
        connector... lo and behold!! I could trigger a few notes on the
     PS-3100
        from Ableton within 45 minutes!
        so my question is - rather than purchasing the rather expensive
     Kenton
        kit (i don't need CC messages, for now....) is there any reason
     at all
        why installing the Arduino with 48 simple 10V transistor gates
     could be
        a bad idea, or potentially dangerous to the instrument?
        it seems like it could be the most minimally invasive procedure
        available for these keyboards....
        thanks for reading...!
        all the best,
